| What Are Lice |
The head louse (plural, lice) is scientifically known as Pediculus humanus capitis, and an infestation with head lice is medically known as Pediculosis capitis.
Head lice are obligate parasites. This means that they cannot survive without a human host—this species can live only on human hosts, so you cannot get them from your dog, cat, guinea pig, or any other kind of furry pet you may have.
Head lice have no wings, so they cannot fly. They have six legs with claws at the ends—that is how they attach themselves to hair.
